Dear OpenSG users, I would like to use the volume rendering in OpenSG with OpenGL shading language. I have to admit that I have difficulties to figure out how the different components work together so I try to avoid writing my own components by subclassing or extending etc ...
I followed the "testSimpleVolumeNode" example checked in on sourceforge. I added a ChunkMaterial (with an SHLChunk) as RenderMaterial to the DVRVolume and this seems "somehow" to work. Unfortunately it seems that from my 4 component image only one component makes it into the shader .... Going back to the original example I realized that it seems to be the same there. It looks like the first component (red ????) is copied into the other components. The image is declared as 4 component image. "imageP->set(Image::OSG_RGBA_PF,res,res,res)" Has somebody a hint how I can fix this, or may be a better way to use shading language with the volume rendering?
